I don't know where you are from, but I think you confuse the word 'coche' with 'gocho'. Gocho is a pig in many Spanish speaking places, not only Guatemala. At the other side, car is called 'coche' in Spain and some American countries, and the most used word in America is 'carro' (also 'auto') but the word 'coche' is also understanded everywhere you speak Spanish. (corrections are welcome)

esto es bonito = this is beautiful (if you don't know the gender of the noun)

Confusingly, in the Spanish words for this/that, they end in "e" if it is male and "o" if it is neutral. And when pluralised there is no "estes". It is "estos".

If there was one thing I would change about the Spanish language it would be eso/esto. I always get them confused. I keep thinking esto = that because they both finish with a t, but obviously, that is incorrect.
